Can you attach the file that makes it crash?

Comment 2 Thomas Vergnaud 2020-06-11 08:18:16 UTC

Created attachment 129221 [details]
fake flac album with tags but no sound

The file is a tar of a music album in FLAC format. Unfortunately I cannot attach the file because it weighs 425 MB. Besides, this might be considered like pirating the album. 
Nevertheless, I attached a "fake" album. It is a tar file that contains FLAC files with no sound, but with the same tags and filenames.

Comment 4 Nate Graham 2020-06-11 12:41:18 UTC

Thanks! And Baloo crashes on this fake archive as well?

> Thanks! And Baloo crashes on this fake archive as well?

I have just tried and downloaded the file; no crash occurred. Maybe the Baloo crash I had encountered was a coincidence and was not related with the file.

Comment 6 Nate Graham 2020-06-12 01:05:10 UTC

Probably.
